Update grub after Manjaro

```

Because I dual boot Linux, after a new install, I always get around to changing

grubs timeout to at least 20 seconds.

In Manjaro I use this command:

sudo nano /boot/grub/grub.cfg

export theme

if [ x$feature_timeout_style = xy ] ; then

set timeout_style=hidden

set timeout=20

Fallback hidden-timeout code in case the timeout_style # feature is

unavailable.

elif sleep --interruptible 5 ; then

set timeout=0

fi

END /etc/grub.d/00_header

```
